Historical bid data is commonly used to define parameters related to the cost of a typical transportation facility construction, Please contact me at. This process uses almost the same tools as expert judgment, analogous estimating, three-point estimating as in the estimate activity duration process. Optimistic (O) – under this, the estimates are based on the best-case scenario. A cost manager can use either one or more of these methods to estimate the costs. Then, for each element, the manager estimates the cost of direct labor, direct material, and other costs. Analogous estimating analyzes a similar project completed in the past and makes a rough estimation for the current project by the use of this past project’s data. It is one of the most accurate methods to estimate the cost. Experts recommend using more than one method as it ensures the accuracy of the estimates. Underestimation of costs and resources makes a contribution to project failure. This method of estimation relies upon a combination of historical data and expert judgment of the project manager.
